Software developers are strongly encouraged by Autodesk to base all future Microsoft Windows based development for AutoCAD based products on the Microsoft .NET Framework (VB .NET, C#, managed C++ etc).

If Autodesk’s future versions (AutoCAD 2013?) still will be able to run VBA or not only future can tell but don’t hold your breath.

JTB World offers fee based porting of LISP or VBA applications to .NET.
